Abstract (en)
[origin: US2014114456A1] Systems and methods are disclosed for synchronizing devices that produce identifiable characteristics from audio media. A device receives audio and produces initial time data. Subsequent time data is received at a coupling interface from a portable device that has access to accurate time sources. The subsequent time data is processed to determine if it is more accurate than the initial time data. If so, the clock of the device is updated to reflect the second time data. The device then processes the audio media to generate at least one identifiable characteristic relating to the audio, which may include ancillary codes and/or audio signatures. The identifiable characteristics are then transmitted together with the subsequent time data for detection.
